The tile holders which came with my Rummikub are subpar, that's what I designed as replacement. <br><br>The mobile version can be assembled and disassembled within seconds, but is not as strong. Use a rasp to make the parts fit, do not press the bars too much, brute force will break the side parts. I recommend to print a few spare side parts for longer journeys.Creative Commons Attribution Noncommercial Share Alike
